dtrace
DTRACE(1) General Commands Manual DTRACE(1)NAME
dtrace - Dtrace compatibile user application static probe generation tool.
SYNOPSIS
dtrace -s file [OPTIONS]
DESCRIPTION
The dtrace command converts probe descriptions defined in file.d into a probe header file via the -h option or a probe description file via
the -G option.
OPTIONS -h generate a systemtap header file.
-G generate a systemtap probe definition object file.
-o file
is the name of the output file. If the -G option is given then the output file will be called file.o; if the -h option is given
then the output file will be called file.h.
-C run the cpp preprocessor on the input file when the -h option is given.
-I file
give this include path to cpp when the -C option is given.
-k keep temporary files, for example the C language source for the -G option.
--types
generate probe argument typedef information when the -h option is given.
EXAMPLES
Systemtap is source compatible with dtrace user application static probe support. Given a file test.d containing:
provider sdt_probes
{
probe test_0 (int type);
probe test_1 (struct astruct node);
};
struct astruct {int a; int b;};
Then the command "dtrace -s test.d -G" will create the probe definition file test.o and the command "dtrace -s test.d -h" will create the
probe header file test.h Subsequently the application can define probes using
#include "test.h"
...
struct astruct s;
...
SDT_PROBES_TEST_0(value);
...
SDT_PROBES_TEST_1(s);
The application is linked with "test.o" when it is built.
